Abstract
A kind of portable later wheel construction is the utility model is related to, mainly solves the problems such as rope, cumbersome for installation, pulley abrasion are squeezed existing for existing later wheel.The structure described in the utility model that later wheel is connected using integral type U-loop with groove profile pulley by lockset screw rod, one end of the U-loop is through hole, the other end is screw thread pin-and-hole, groove profile pulley is connected with U-loop by lockset screw rod, pulley wheel along with it is seamless between U-loop, 1 2mm gap is left between pulley axle portion and U-loop, respectively there are the thick packing rings of 1 2mm flute profile pulley axle portion both sides, flute profile pulley wheel is more than pulley axle portion width along width, U-loop is welded with gear rope bar close to bending section position, and gear rope pole length is less than U-loop inboard width.Should later wheel have it is simple in construction, mount conveniently, intensity is big, anti abrasive advantage.
Description
Technical field
The utility model is related to a kind of later wheel construction for lifting winch delivery and using, more particularly to it is a kind of it is portable later
Wheel construction.
Background technology
In traditional underground coal mine winch, haul large scale equipment or general hoisting process, what is typically used later takes turns, mainly
By hook, connecting pin, rope blocking plate, pulley, due to complicated, when using larger, when later taking turns, one can not typically complete
Suspension, adding work difficulty reduces operating efficiency.
Existing later wheel construction is " Ω " shape ring structure, in pulley wheel along with being left between " Ω " shape ring compared with big gap, is held
Easily cause and squeeze rope phenomenon, while there is no gap to cause to change larger, the shortening that rubs when wheel rotates between pulley axle portion and " Ω " shape ring
The later service life of wheel.It is existing later to take turns mostly using the form of hook, when pulling force is larger or often leads during unbalance stress
Cause later wheel unhook.
And baroque later wheel is extremely difficult to the requirement of intensity, therefore a kind of portable later wheel construction is designed,
Only turn one's head wheel by lockset screw rod, U-loop and groove profile pulley to form, U-loop increases structural strength using integral structure, more square
Just hang.Pulley wheel coordinates gear rope bar to avoid and squeezes rope and tow strap problem, pulley axle portion and U along with being left no gaps between U-loop
Gap is left between shape ring and cushioning circle reduces friction, extends the service life of later wheel construction.
Utility model content
The utility model mainly solves the problems, such as that existing later take turns squeezes rope, unhook problem and pulley friction problem, and this practicality is new
Type provides a kind of portable later wheel construction.
The technical solution of the utility model is：
A kind of portable later wheel construction, including lockset screw rod, U-loop and groove profile pulley are later taken turns, it is characterised in that institute
State U shapes ring and use integrally formed structure, one end of U-loop is through hole, and the other end is screw thread pin-and-hole；The lockset screw rod is successively
Connect the screwed hole of the through holes of U shape rings, groove profile pulley and U-loop, the wheel of flute profile pulley along and seamless, flute profile between U-loop
1-2mm gap is left between the axle portion and U-loop of pulley, respectively there are the thick packing rings of 1-2mm, flute profile in the axle portion both sides of flute profile pulley
The wheel of pulley is equal with U-loop inboard width more than flute profile pulley axle portion width along width；The U-loop is close to the position of bending section
Put and be welded with gear rope bar, gear rope pole length is less than U-loop inboard width.
Lockset screw rod one end described in the utility model has handle hole, and middle part carries the annular line less than 1mm, other end end
Portion is machined with external screw thread；The width in gap is equal with gasket thickness between the flute profile pulley axle portion and U-loop, is padded by changing
Gap width between circle regulation flute profile pulley spindle portion and U-loop.The U-loop bending section is machined with annular pattern projection.
The utility model effectively solves the problems, such as that existing later wheel construction easily occurs squeezing rope, alleviates pulley and U
Friction between shape ring, the service life later taken turns is extended, structural strength is increased using integrally formed U-loop suspension,
Avoid unhook problem.It is described in the utility model simple in construction, it is easy for installation.
Brief description of the drawings
Fig. 1 is portable later wheel construction front view；
Fig. 2 is portable later wheel construction side view；
In figure：1- flute profile pulleys；2- gear rope bars；3-U shape rings；4- lockset screw rods；5-packing ring.
Embodiment
With reference to shown in Fig. 1 to Fig. 2, a kind of portable later wheel construction embodiment is as follows：
A kind of portable later wheel construction, including packing ring 5, lockset screw rod 4, U-loop 3, gear rope bar 2 and groove profile pulley 1, its
It is characterised by, the U-loop 3 uses integrally formed structure, and one end of U-loop 3 is that the through hole other end is screw thread pin-and-hole；The groove
Type pulley 1 is connected with U-loop 3 by lockset screw rod 4, and respectively there are the thick packing rings 5 of 1-2mm the axle portion both sides of flute profile pulley 1, and flute profile is slided
The wheel of wheel 1 is equal with U-loop inner distance more than pulley axle portion width along width；Wheel edge and the U-loop 3 of the flute profile pulley 1
Between it is seamless, 1-2mm gap is left between the axle portion and U-loop of flute profile pulley 1；The U-loop 3 is close to bending section position
Gear rope bar 2 is welded with, gear rope pole length is less than U-loop inboard width.Packing ring 5 described in the utility model using rubber washer or
Spring washer, described one end of lockset screw rod 4 have handle hole, and other end end is machined with external screw thread, the pulley axle portion and U-shaped
The width in gap is equal with gasket thickness between ring.
The portable later wheel construction when in use, mounts U-loop 3 first, by control keep off rope bar 2 and U-loop 3 it
Between gap ensure mount stability, occur unhook problem after preventing；Flute profile pulley 1 is placed in the opening of U-loop 3 and cunning again
Axle hole aligns with the mounting hole of U-loop 3, and lockset screw rod 4 sequentially passes through mounting hole, packing ring, pulley axis hole, packing ring, screw thread installation
Hole, lockset screw rod is screwed using lockset screw action hole.
